how to better your gas mileage with out buying a new car

in todays economy gas prices are alot higher then they use to be back in the day. about twenty years ago they where around 1 dollar. today they average around 2.75 a gallon. the goverment stepped in and instead of tell the oil companys to lower there already high oil prices they decided to crack down on teh car companys. they told chrysler and General Motors and Ford to start making lower end cars that were more fuel efficient and less pricey to compete with toyota and honda. so those car companys went to the drawing board and came out with hybrids to compete with the other car companys. with the gas prices rising and people not making enough money to keep filling there cars up all the time they started to buy more fuel efficient cars.
this is the reason the government started the cash for clunkers. well believe it or not it was more expensive to trade in or sell your car you had,if you where still making payments on it, and buy a new car. the only time it was worth buying a new hybrid was if you already had your car paid off that you where driving. so if you are reading this and you are still making paymenys on a SUV or something that doesnt get good enough gas mileage for you and you want to buy a new car. DONT! unless you are rich and can afford it, it is not worth replacing your car with a new hybrid. i am about to tell you how to turn your gas guzzler into a hybrid that isnt as expensive as buying a new one and going through all the hastle of trying to sell your own car.
First you can start off by replacing your stock air filter with a K&N air filter or a cold air intake. this allows your engine to breathe more and perform better. when you buy a new car the air filters are cheap and made of paper and starve your engine of air. this makes robs your engine of power and gas mileage which in the long run is bad and ends up costing you more money. with these two types of air filter up grades you are now allowing your engine to breathe and retain more air. when you get more air to the engine and at a faster rate and higher vilosity you end up getting a better fuel to air mixture ratio. this allows the combustion of the new and improved mixture to be more substantial and powerful resulting in more horsepower. this also allows the computer to recognize that more air is coming in and starts useing less gas,which in return gets your vehicle better gas mileage and enables your engine to run longer.
